Then, you don't know this fanbase very well. Last year, Howard Simon posted an article around October/November where he said "we need to seriously start talking about Tyree Jackson if Allen doesn't show improvement down the stretch." That's a long-time member of the local media who openly stated that he was willing to give up on Allen after 1 year (granted, Howard hated the Allen pick and went so far as to say that he "didn't want to talk about it" on the morning after last year's draft).
One interception from Allen in pre-season will be enough to have fans and media going "oh, boy. who are the top QBs coming out in 2020?"

Beane: Rick, Tyler Kroft just broke his foot in practice and we need to add another tight end. Now, I understand that you've indicated that Kyle Rudolph might be available for a trade. What compensation are you looking for?
Rick Spielman: Give me your 2nd round pick in 2020 and you've got a deal.
Beane: That seems a bit high.
Spielman: Take it or leave it. Not sure if you've checked the news, but the Patriots have reached out to us about Kyle.
Beane: You've got a deal! A 2020 2nd it is.
Spielman: Care to throw in a mid-round pick as well? Maybe a 5th?
Beane: Agree to that as well. We can't let him go to New England. Thanks, Rick.

Who's "we?" Doug Whaley and Rex Ryan (paragons of personnel management) moved on from Lee Smith, not Beane and McDermott.
Now, if Beane had released him in 2017 and are now bringing him back, then I'd be concerned.
